Data services via wireless networks and mobile devices have experienced rapid growth worldwide. We investigated the factors influencing adoption of wireless mobile data services (WMDS) in China and tested our model for explaining adoption intentions there. We argued that individuals form their intention to adopt WMDS under the influence of wireless mobile technology, the social environment, personal innovativeness of IT, trust awareness, and the facilitating conditions. We examined the simultaneous effects of these five influences on beliefs in the context of wireless Internet data services via mobile phones. Survey data were collected from 1432 participants in several metro cities across China. The findings suggest that WMDS adoption intention in China is determined by consumers’ perceived usefulness and perceived ease of use of WMDS. Theoretical and practical implications are included in our paper. 相似文献

Data from a 25-year prospective study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable adults at age 33. Profile analyses revealed two behavioral types in childhood and two personality types in adulthood, with considerable continuity in the composition of these high- and low-agreeable types over time. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types, and among boys, high-agreeable childhood types had better school grades and fewer behavior problems than their low-agreeable counterparts. High-agreeable adulthood types reported less alcoholism and depression, fewer arrests, and more career stability than did low-agreeable adulthood types.

Theory suggests that cigarette smoking is under stimulus control and that affect is a key trigger for smoking. A previous study (S. Shiftman et al., 2002) showed little relationship between affect and smoking, but this relationship could have been suppressed by the impact of smoking restrictions. The study evaluated these associations in a 1988 sample that was subject to few smoking restrictions. Smokers (N = 28) not seeking treatment used palmtop computers to record context and affect prior to smoking (n = 2,217 observations) and also at random times when not smoking (n = 2,380). Comparisons showed little relationship between smoking and affect. Smoking was associated with particular activities and locations. Urge to smoke was the strongest predictor of smoking. The results replicated the findings of S. Shiffman et al. (2002). (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Transformational leadership and group interaction as climate antecedents: A social network analysis.
In order to test the social mechanisms through which organizational climate emerges, this article introduces a model that combines transformational leadership and social interaction as antecedents of climate strength (i.e., the degree of within-unit agreement about climate perceptions). Despite their longstanding status as primary variables, both antecedents have received limited empirical research. The sample consisted of 45 platoons of infantry soldiers from 5 different brigades, using safety climate as the exemplar. Results indicate a partially mediated model between transformational leadership and climate strength, with density of group communication network as the mediating variable. In addition, the results showed independent effects for group centralization of the communication and friendship networks, which exerted incremental effects on climate strength over transformational leadership. Whereas centralization of the communication network was found to be negatively related to climate strength, centralization of the friendship network was positively related to it. Theoretical and practical implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Using ambulatory methods for 1 day of monitoring, the authors of this study investigated the association between smoking and situational cues in 63 smokers with posttraumatic stress disorder (PTSD) and 32 smokers without PTSD. Generalized estimating equations contrasted 682 smoking and 444 nonsmoking situations by group status. Smoking was strongly related to craving, positive and negative affect, PTSD symptoms, restlessness, and several situational variables among PTSD smokers. For non-PTSD smokers, the only significant antecedent variables for smoking were craving, drinking coffee, being alone, not being with family, not working, and being around others who were smoking. These results are consistent with previous ambulatory findings regarding mood in smokers but also underscore that, in certain populations, mood and symptom variables may be significantly associated with ad lib smoking.

Using a sample of U.K. wire makers (N = 282), the authors tested a model in which personality and work environment antecedents affect proactive work behavior via cognitive-motivational mechanisms. Self-reported proactive work behaviors (proactive idea implementation and proactive problem solving) were validated against rater assessments for a subsample (n = 60) of wire makers. With the exception of supportive supervision, each antecedent was important, albeit through different processes. Proactive personality was significantly associated with proactive work behavior via role breadth self-efficacy and flexible role orientation, job autonomy was also linked to proactive behavior via these processes, as well as directly; and coworker trust was associated with proactive behavior via flexible role orientation. In further support of the model, the cognitive-motivational processes for proactive work behavior differed from those for the more passive outcome of generalized compliance.

Data gathered from mothers on parenting and family climate when almost 1,000 children in the Dunedin, New Zealand, longitudinal study were 3, 5, 7, 9, 13, and 15 years of age were used to predict intergenerational relations between young adult children (age 26) and their middle-aged parents. Analyses focused on distinct developmental epochs revealed greater prediction from the middle-childhood and early-adolescent periods than from the early-childhood years; most indicated that more supportive family environments and child-rearing experiences in the family of origin forecasted more positive and less negative parent-child relationships (in terms of contact, closeness, conflict, reciprocal assistance) in young adulthood, though associations were modest in magnitude. Some evidence indicated that (modestly) deleterious effects on intergenerational relations of experiencing relatively unsupportive child-rearing environments in 1 but not 2 (of 3) developmental periods studied could be offset by relatively supportive family environments in the remaining developmental periods.

Developmental antecedents to adult emotional functioning were investigated in an epidemiologic study using theories of personality and emotion. The authors tested whether different types of adult emotional distress can be linked to childhood personality attributes. Using data from 3,138 children at age 7, measures of 4 childhood personality attributes were developed and validated: Behavioral Inhibition, Distress Proneness, Attention, and Inappropriate Interpersonal Self-Regulation. Sound psychometric properties of these scales are demonstrated by considering the measures across multiple samples and in comparison with established child behavior measures. Emotional distress measures were obtained for 694 of these individuals at age 35. Of the personality attributes, 3 of 4 (except behavioral inhibition) predicted general levels of distress as well as specific aspects of ioral adult emotional functioning.

Cyberloafing in the knowledge-intensive settings has hitherto remained an underexplored research terrain. This is despite that, among others, the implications of cyberloafing in the knowledge-intensive context are more costly to the employers as compared to other less-knowledge-intensive settings. The motivations, moderators and consequences of cyberloafing among knowledge workers appear to have multifarious differences and contextual nuances. One of the significant determinants and increasing vulnerabilities of the knowledge-intensive setting is job burnout. This paper particularly focuses on and studies the inter-relationship of job burnout and cyberloafing. The viewpoints of knowledge-workers at a cross-section of organizational levels have been studied through quantitative surveys. The findings show that both facets of cyberloafing (activities and behaviors) have significant impact on job burnout among knowledge workers. It is also proved that cyberloafing ‘behaviors’ is a stronger predictor of job burnout than cyberloafing ‘activities’. 相似文献
